An electric dipole consists of two electric charges of equal magnitude and opposite sign. If the charges are q and -q and are located at a distance d from each other, then the electric field E at the point P in the figure is
By expanding this expression for E as a series in power of d/D, show that E is approximately proportional to 1/D^3 when P is far away from the dipole.
